ELMER J. JONES, OF DENVER, COLORADO.

DEVICE FOR REGISTERING WOOD-BASE CUTS 0N PRINTING-PRESSES.

srscmronrion forming part of Letters Patent No. 728,723, dated May 19, 1903.

Application filed Jnne ZO, 1902.

T0 at whom it may concern:

Be it known that I, ELMER J. JONES, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Devices for Registering Wood-Base Outs on Printing-Presses; and I do declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

My invention relates to a device for registering wood-base cuts on printing-presses, especially adapted for registering color-plates where several impressions are to be run in difierent colors of ink.

The objects of myinvention are to provide a register for cuts that will facilitate the use of the cuts as they come-from the factory mounted upon a wood base; one that will dispense with the remounting of the cuts on metal bases or expensive patented bases; one that makes a light form for the press, and hence one that can be run at a greater speed than when the forms are heavy, as is the case when metal bases are used; one that can be very quickly adjusted, also one that provides. efficient means forsuccessfully registering the cuts at any desired angle; one that obviates the necessity of unlockingthe forms to register the cuts; one in which every out is entirely separate from other cuts placed within the same chase; one which dispenses with the flexibility of the form, and one which can be adjusted to fit any-sized cut in a very short space of time.

The foregoing objects are attained by the construction illustrated in the drawings, in which- Figure. 1 is a perspective View of a form mounted within a chase embodying my invention. Fig. 2 is a view of one of the cornerplates. Fig. 3 is an isometrical view of one of the registering devices. Fig. 4 is a modified view of same.

In further referring to the drawings, A represents an ordinary chase used in looking up any kind of a form.

Serial No. 112,477. (N0 modelL B represents a wood-base out of ordinary construction.

0 indicates the registering devices, one of which is placed in a position to operate against each corner of the out. These registering devices are constructed of right-angled parts, as illustrated. Each part has a recess or depression,(represented by C1 in the different figures of the drawings.) An internallythreaded aperture is provided through these corner parts from the recessed portion, in which operates an externallythreaded thumb-screw, (represented by C in the different figures of the drawings.) The registering devices 0 are provided with offsets O on their inner surfaces and the internallythreaded apertures pass through the offsets, which afford a greater bearing-surface for the thumb-screws C? and operate to strengthen the construction and prevent the stripping of the threads. The thumb-screws are beveled or conical-shaped on the end of the screw portion. The heads of the thumbscrews are providedwith numerous recesses or depressions, (indicated by C facilitating their adjustment by means of the insertion into such depressions of some flat instrument or tool especially constructed 'for the purpose.

D represents corner-plates bent to form right angles, as fully illustrated in Fig. 2 of the drawings. These corner-plates are ad apted to be placed around the corners of the cuts and to provide a metal base for receiving the thrust of the beveled or conical points of the thumb-screws 0 as will be made manifest by consulting Fig. 1 of the drawings.

E represents ordinary furniture used in looking up the form.

F represents furniture used in properly spacing the registering devicesyso that they can be adjusted to fit any-sized cut.

G represents the lockable quoin used in locking up forms; but I do not claim anything thereon, as they are covered by prior Letters Patent and do not form a part of the subject-matter of this application.

The material from which my new registering devices are constructed is any suitable metalyeither bronze, brass, or steel, as I do not confine myself to any one metal nor to any one manner of constructing the device, but desire to cover by Letters Patent the principle involved and construct it according ordinary manner and the registering devices spaced to fit the cut by means of the furniture, (represented by F.) The cut is then placed within the space provided therefor, and by means of the thumb-screws 0', provided in the registering device 0, the cut can be registered in the very finest possible manner, the corner plates first being placed around the corners of the cuts against which the conical or beveled points of the thu mbscrews operate. I

Having thus described the nature and objects of my invention with the manner of constructing and applying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination within a chase with the usual furniture, of a work-registering device comprising a block having a recess formed therein and internally-threaded apertures connecting the recesses with the periphery of the block, integral adjustable means received within the apertures and recesses, the inner ends of the adjusting means contained entirely within the periphery of the block, the opposite ends of the adjusting means extending through the apertures and outside of the block and adapted to engage the work to be registered.

2. The combination within a chase, with the usual furniture, of a device for registering the work relative to the chase, the device comprising a plurality of angled movable blocks located at and embracing the corners of the work, bearings formed in the blocks, adjusting-screws carried by the blocks, the

' heads of the screws located entirely within the peripheries of the blocks, the screws received and operating in the bearings in the blocks and angled plates received upon the corners of the work, the inner ends of the screws bearing against the plates.

3. The combination within a chase,with the usual furniture, of a work-registering device comprising a plurality of suitablyform ed blocks adapted to embrace the corners of the work,the blocks having recesses formed therein and internally-threaded apertures connecting the recesses with the inner peripheries of the blocks, screws operating within the apertures and recesses,the screws adapted to move longitudinally relative to the blocks, the heads of the screws provided with means for permitting the rotation thereof, and plates, the contours of which correspond to the shape of the blocks,the plates adapted to embrace and rest upon the corners of the work to be centered.

4. In a device for registering cuts, the combination with a chase and furniture, of angled blocks having recesses formed therein, screws operating within the recesses,and angle-plates located around the corners of the cut to be registered, the plates adapted to receive the end thrustof the screws which bear thereagainst, the heads of the screws having depressions formed therein for facilitating the use of an instrument in the adjustment of the screws.

5. In a device for registering cuts, the combination with a chase and form comprising suitable furniture and locking devices, of registering devices consisting of right-angled blocks having recesses formed therein, screws operating within the recesses, and cornerplates located at the corners of the cut to receive the end thrust of the screws.

6. In a device for registering cuts, the combination with blocks having apertures therein, screws received and operating in the apertures, the blocks locked up within a suitable chase by means of ordinary furniture and locking devices with the cut to be registered, and movable plates located against the sides or edges of the cut and adapted to receive the thrust of the screws.

7. The combination within a chase, with suitable fu rniture,of a registering device comprising a plurality of movable blocks having recesses formed therein and screw-threaded apertures connecting the recesses with the inner peripheries of the blocks, of adj ustingscrews received within the recesses and apertures, the screws movable longitudinally with relation to the blocks and plates of similar form as the blocks, the plates adapted to embrace the corners of the cut to be registered, the screws provided with conical inner ends which bear against the plates to efiect the adjustment of the cut, the blocks being entirely independent of the chase.

8. In a device for registering woodbase cuts, the combination with movable angled blocks having recesses formed therein,thumbscrews operating in the recesses, the blocks locked up within a suitable chase by means of ordinary furniture and locking devices, the cut to be registered provided with movable corner-plates adapted to receive the thrust of the ends of the thumb-screws, the blocks being independent of the chase.

In testimony that I claim the foregoing as my own I hereunto subscribe my name in the presence of two witnesses.

ELMER J. JONES.
